I have created a simple app for a friend and people quite loved it.

I recently started a youtube channel(https://www.youtube.com/channel/UC1WpgYEx7hhEIaLLtJ2C2sA) showing people how easy to create basic apps for business using glideapps. Right now the videos are in Hindi but planning to release in English as well.
